palera1n is both a tethered and a semi-tethered jailbreak for devices vulnerable to the checkm8 bootrom exploit running iOS/iPadOS 15.0-17.3. This jailbreak supports both rootful and rootless modes via an argument (apart from iOS/iPadOS 17, which only officially supports rootless mode).

palera1n Legacy (or 1.x) is deprecated and no longer maintained by it's original authors due to the introduction of palera1n-c (or 2.0.0 beta), which utilizes checkra1n's 0.1337.x builds to boot into pongoOS - however, using its own components (such as binpack, overlay, kpf, fork of pongoOS) to help it boot into the jailbroken state.

Due to the nature of checkra1n, palera1n-c (or 2.0.0) dropped support on making an option for it also to be a tethered jailbreak, unlike palera1n Legacy (1.x) which doesn't use checkra1n.

Supported devices

Note: On A10(X) and A11 devices, the passcode must be disabled while in a jailbroken state. On iOS 16, those SOCs require erasing the device before use. Using palera1n 2.0.0 allows the use of a passcode if on A10(X).

Highlighted changes

  • Support for 17.0 - 17.1 (and potentially higher)

    • Proper documentation for this soon.


  • Downloaded content is now in /tmp/ due to potential permission issues from other jailbreaks.
  • Changes some loader internals to accommodate for json loading changes, this includes having some optimizations for the interface.
  • Cleanup of useless files/directories being created that were there for development purposes.
  • Upon using --force-revert, --clean-fakefs, and "Revert Install", it now deletes leftover Zebra files.
  • Helper will no longer try to write to Zebra's sources.list to add palera1n's default repositories, rather now you should use Zebra's built in community sources page for default repos.
